[Add] draft-stark-add-dns-forwarder-analysis

[Chris Box <[e-mail]>]

All,

As you know the WG's recent progress has been mainly on DDR and DNR.
Barbara has spent some time considering what these drafts would mean for
typical residential deployments. The results can be found in the new I-D
draft-stark-add-dns-forwarder-analysis-00
<https://datatracker.ietf.org/doc/draft-stark-add-dns-forwarder-analysis/>.

   This draft analyzes the behaviors that residential end users and home
   network owners (e.g., parents of young children) might experience
   when operating systems and clients support [I-D.ietf-add-ddr] and/or
   [I-D.ietf-add-dnr] for discovery of encrypted DNS services and the CE
   router of the home network offers itself as the Do53 resolver.  This
   use case is explicitly mentioned in [I-D.ietf-add-requirements]
   Section 3.2 and has several requirements related to it.  This draft
   has two goals: determine if the analysis it provides is accurate and,
   if it is accurate, determine if the behavior is acceptable to the WG
   or if there should be changes to either of the discovery mechanisms.

We *think* the conclusions are valid for both ddr-01, and ddr-01 with PR#11.

But the purpose of writing this draft is to get your opinion. Are we wrong?
If so in which way?

Or if we are not wrong, the final question is to ask you if you are happy
with that end result.

Please have a look and let us know.
